E YEGLASS AND SPECTACLE MOUNTING- Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed February 19,1906. Serial No. 301,874.

To all whom it may concern:

'Be it known that I, EDGAR J.-GEOr.en, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented certain newand useful Improvements in Eyeglass and Spectacle Mountings, of whichthe ollowing is a specification.

This invention relates, primarily, to the subject of eyeglass andspectacle mountings, although its uses are not necessarily confined tothat particular art.

The'principalobject of the invention is to dispense withremovably-inserted fastenings, such as the ordinary small screw, forsecuring together the lensv of an eyeglass or spectacle and thestud-straps of a skeleton mounting. Such fastenings are inclined to workloose and require constant readjustment in order to firmly hold the lensin its proper position with relation to the mountin The presentinvention does away entirely with any such form of fastening, and henceefiectually cures the defect of looseness between lens and mounting.

More specifically stated, the object of the invention is to unite thelens and the mounting by means of a substance which may be applied influid form through the orifice of the stud-strap and will adhere to thelens and solidify over the sides of the said orifice.

Having thus indicated. the objects and purposes of the invention, it maybe said to consist in the. manufacture specified in the appended claims.These claims point out the characteristic and essential elements in themanufacture, while the accompanying drawings illustrate a preferred formof the embodiment of the invention.

Of these drawings, Figure 1 represents in rear elevation a pair ofeyeglasses with skeleton mountings secured to the lenses by the use ofthepresent invention. Fig. 2 represents one of the studs on a largerscale with a fragment of a lens, and Fig. 3 represents the same parts ona still larger scale and in longi- :tudmal sections.

In the said drawings the reference-letter a designates theeyeglass-lenses; l), the spring or'nose-piece mounting; c, thenose-guards; (l, the studs to which. the said spring and nose-guards aresecured, and a the straps formed integral with the studs and overlyingthe opposite sides of the lens. These straps are ordinarily made withorifices through which small screws are inserted, the orifice in onestrap of a stud being countersunk to accommodate the head of the screwand the orifice in the other strap of said stud being screw-threaded tocooperate with the shank of the screw and the lens being drilled for thepassage of the screw which operates to clamp the lens between thestraps. In the form here shown the straps are triangular in outline andthe orifice is likewise triangular, the inside edges of the metalforming the triangle being beveled, as shown at e in Fig. 3, so as tomake the orifice countersunk.

In carrying out the present invention in the form here shown both.straps of the stud are of the above-- described construction. The lensto be secured between these straps does not require boring, as the lensand the straps are not united by means of a fastener necessarily runthrough the lens. Silicate of potash or soda, commonly called liquid orwater or soluble glass, is employed as abinder for uniting the lens andthe straps. The lens is properly adjusted between the straps and thenthe liquid glass is dropped into the orifice of the strap in sufl'icientquantity to slightly exceed the capacity of the orifice. The liquidglass will be dropped into the orifice in the form of a globule, whichwill rise slightly above the level of the outer surface of the strap.This form of binder applied inv the fluid state will of course entirelyfill the orifice of the strap, and inasmuch as the quantity used,slightly exceeds the capacity of the orifice the contraction whichaccompanies the solidifying of the fluid will still leave the latterinclose engagement with the beveled sides of the metal.

At the same time the substance adheres strongly to the surface of thelens, and it will be obvious that by such means an absolutely firmcom'iection is made between the lens and the strap. The quantity of theliquid glass US-Ctl is so calculated to provide for its coming llushwith the outer surface of the strap when. solidified. 1n the drawingsref-- erence-lctterf designates a binder produced in this manner on bothsides of each lens. in the case of spectacles the temple-studs as wellas the nose-pieces would also be secured to the lens by the sameprocess.

It will be seen that the abovedescribed method oi uniting glass andmetal is perfectly adapted to accomplish the objects heretofore setforth, and it will now be further apparent that the invention is notnecessarily confined to theeyeglassand spectacle art. Neither is theinvention confined to the onesubstance herein specified, it being sufiicent for the general purposes of the invention to emplo any substancewhich can be used In fluid orm and which will adhere to glass. It'is notof course necessary for the substance to adhere also to metal. In fact,

the particular substance above specified does not adhere'to metal; butthe binding of the metal to the glass is insured by the=substance sohdfying over the countersunk portions of the metal. It is of coursedesirable to employ-a substance which is soluble, so as to facilitatereplacement of broken lenses withoutre uiring new mountings. Thesubstance erein specified is soluble, and hence its use broken lenses bynew lenses in the same mountings. This particular substance also has theadvantage of being transparent, like the lenses themselves.
